| Abstract: | In the real digital baseband communication systems,for succeeding in transmitting information in baseband channel that we have to select a suitable baseband signal,the HDB3 baseband signal is the most choosing signal among all.The paper adopts VHDL in the Max-plus II programming environment based on the characteristics of the HDB3 in digital baseband transmission systems and CPLD/FPGA,which has made the HDB3 encoder and the decoder.The experimental result shows that the HDB3 baseband signal the encoder and the decoder systems are simple and reliable,through which can transfer original information into HDB3 baseband signal conveniently. |
